When I run the code for my network, I keep getting this error.
Error using 'backwardLoss' in Layer ctcClassificationLayer. The function threw an error and could not
be executed.
I do not understand how this equation works
labelIdx = labelIdx + layer.Categories(maxIdx);
why is a categorical value getting added to a numerical index?
